Policy

Conclusion:

The board (has, has not) established effective policies

relating to the bank’s derivatives activities.

Objective:

To evaluate the adequacy of derivatives policies relating to

price risk.

1. Evaluate the adequacy of price risk management policies and

procedures. Determine if they:

• Require annual board approval.

• Require preparation and distribution of position reports by an independent party, without intervention by the trader or risk-taking unit.

• Require timely notification of actual or probable limit exceptions.

• Require prompt consideration of all limit exception requests (generally, approvals should be obtained from the next higher level of management).

• Address monitoring and tracking of limit breaks and exception approvals.

2. Determine whether management’s policy for review and

updating of assumptions underlying the pricing, revaluation, and risk measurement models is reasonable. Determine whether management complies with the policy.

Objective:

To evaluate the adequacy of derivatives policies relating to

liquidity risk.

Processes

Conclusion:

Management and the board (have, have not)

implemented effective processes to manage derivatives activities.

Objective:

To determine the adequacy of processes relating to

management of price risk in derivatives activities.

1. Evaluate the manner in which trading strategies are

formulated, executed, and monitored. Consider the following:

• Line management’s day-to-day oversight of trading activities.

• The limits and restrictions on delegated authorities.

• Requirements for approving trading in new products, markets, and extended maturities.

• Management’s authority and willingness to modify or override trader decisions (using offsetting positions or specific instructions).

• Modifications in varying market conditions.

2. Obtain a list of recent price risk limit exceptions. Determine

whether the exceptions were identified and approved on a timely basis. Determine whether the basis and timeliness of approval were reasonable and within the approver’s authority. Evaluate the level and nature of the exceptions.

3. Determine that the types of pricing models used and their

capacities are appropriate for the nature and volume of business conducted. Determine the person(s) responsible for developing and maintaining the models.

4. Evaluate the method used to measure price risk exposure.

Determine who developed and maintains the system. Assess whether the method is commensurate with the nature and complexity of the activity conducted. Determine whether:

• Price risk is measured on a desk, country, regional, and global basis.

• The bank’s systems can aggregate price risk exposure across all products, desks, branches, and globally.

• The method considers the characteristics of the underlying instruments in view of the following:

– Tenor of the instrument.

– Changes in price under varying market conditions, in

response to changes in liquidity, etc.

– Estimated holding period or time to close or hedge the

position.

• The methodology expresses risk as a percentage of current

earnings or capital.

• The exposure arising from a change in applicable major market factors, such as interest rates, foreign exchange rates or market volatility, can be aggregated, evaluated, and reported in a timely manner.

• The system facilitates stress testing.

5. If the price risk measurement system does not include all

sources of price risk exposure, estimate the percentage of risk

Comptroller’s Handbook 107 Risk Management of Financial Derivatives

captured by the system. Determine whether senior

management is aware of coverage levels and if the omissions are reasonable in view of the circumstances.

6. Determine whether management performs adequate stress

testing. Evaluate:

• The basis for stress scenarios.

• The reasonableness of stress scenarios.

• Whether the frequency of stress testing is appropriate.

• Whether stress tests incorporate the interconnectedness of risks.

• Whether senior management and the board are apprised of the results of portfolio stress testing.

Objective:

To determine the adequacy of processes relating to

management of liquidity risk in derivatives activities.

1. Determine whether the bank maintains closeout cost reserves. If so, determine whether the method for calculating the

reserve is reasonable.

2. Determine that the bank’s liquidity risk management function

has a separate reporting line from traders and marketers. 3. Ascertain whether good communication exists between

derivatives managers and persons responsible for domestic and foreign currency funding.

4. Review the bank's contingency liquidity plan to ensure that it

includes derivatives. This step should be coordinated with the examiner assigned to review “Liquidity.” Determine if the plan:

• Addresses potential market liquidity and cash flow funding aberrations for both on- and off-balance-sheet instruments.

• Requires projections of cash flows (including asset usage from credit enhancements) under normal and stressed market conditions. Individual bank and system liquidity

crises should be projected.

• Assigns specific duties and responsibilities to individuals to manage derivatives in the event of deteriorating, as well as crisis, situations.

• Addresses the impact of collateral requirements and early termination requests.

Objective:

To determine the adequacy of processes relating to

management of foreign currency translation risk in derivatives activities.

1. Review the bank’s systems to determine the timeliness and

completeness of the information used to make cross-border investing and hedging decisions.

Objective:

To determine the adequacy of processes relating to

management of credit risk in derivatives activities.

1. Evaluate the process for determining whether a derivatives

transaction is appropriate for the counterparty. Select a sample of recent derivatives transactions. The sample should focus on nondealer counterparties and include:

• Contracts with large mark-to-market values (both positive and negative).

• Complex, leveraged, and plain vanilla transactions.

• Off-market, extended, or terminated transactions. 2. Review both the credit and marketing files for sample

transactions to assess the adequacy of documentation

relating to determining appropriateness. Discuss the sampled transaction with the responsible credit and/or marketing

officers. Determine if:

• Credit files contain sufficient information to

understand the risks the customer is attempting to manage,

Comptroller’s Handbook 109 Risk Management of Financial Derivatives

types of derivatives expected to be used, and the overall impact on the customer.

• Marketing files contain information on the transaction and any disclosures given to the customer (e.g., customer profile information, deal term sheets, sales presentations, scenario analysis, correspondence).

3. Evaluate the adequacy of the credit risk measurement method

used to calculate presettlement credit exposure through

review of model information and discussions with management. Determine if:

• The system produces a reasonable estimate of loan-

equivalent exposure including the current exposure (mark- to-market) plus an estimate of the potential change in value over the remaining life of the contract (add-on).

• The credit risk add-on calculation is:

– Statistically derived from market factors.

– Consistent with the probability modeling used to

evaluate price risk, except that the add-on calculation will use the remaining life of the contract as a time

horizon.

– Based on peak exposure.

• The frequency of credit calculations is adequate.

• The bank maintains documentation to support that the assumptions used in the credit risk exposure calculation are updated as appropriate.

4. Review the credit risk measurement method used to calculate

settlement exposure, and determine that it provides a reasonable estimate of risk.

5. Determine the degree to which the credit risk measurement

system can aggregate credit exposure, on both a gross and net basis, across desks, branches, and/or globally.

6. Determine the extent to which management uses settlement,

closeout, or multilateral netting arrangements. Determine:

• Whether the bank’s operational systems can accommodate netting.

• Whether counterparty payments or credit exposures are netted for purposes of computing periodic settlement or reporting aggregate credit exposures.

• The process whereby management ensures that a signed master agreement is on file before netting is performed. Evaluate the bank's system to track and resolve unsigned master agreements.

7. Select a sample of counterparties where credit exposure is

netted. Trace to supporting master agreements to ensure that each counterparty with which management nets exposure for risk management purposes has signed a master agreement. 8. Obtain a list of recent credit limit and policy exceptions.

Determine whether the exceptions were identified and approved. Determine whether the basis and timeliness of approval was reasonable and within the approver’s authority. Evaluate the level and nature of the exceptions.

9. Determine how the credit risk control function notifies traders of

deteriorating trends in a counterparty’s financial condition or changes in limits. Also determine how traders communicate their knowledge of counterparties’ deteriorating financial condition to the credit risk control function.

10. Determine whether there have been any recent counterparty

credit downgrades or deteriorations affecting the bank's trading activities. If so, determine the bank's response. 11. Determine how the bank identifies and reports past-due

counterparty payments. Review the bank’s past due, watch list, or deteriorating trend reports. Discuss management’s workout strategy for these counterparties.

Comptroller’s Handbook 111 Risk Management of Financial Derivatives

12. Determine whether the bank maintains credit reserves for

counterparty exposures apart from the allowance for loan losses. Determine whether the method for calculating the reserves is reasonable.

13. Determine whether appropriate bank personnel have

reviewed the counterparty’s agreement with the investment advisor to assess the type of activities that are authorized or prohibited.

14. Determine whether senior management and credit risk

management have assessed credit risk exposure arising from
